Compression test
 

I currently have my engine out and sat on a trolley on the floor. I was wondering if it's viable to do a compression test now with the engine sat on the trolley? I was thinking of pulling all the plugs so compression and movement is minimal and then applying 12 volts directly to the starter.

Anyone think this is a bad idea?

Not without oil circulation.

You can do a leakdown test with it out.

So 5 turns per cylinder under the power of the battery is too risky without oil?
